roblem The graph shows the tide level in Daytona Beach on a certain day. Time is measured in hours after midnight and the height of the tide is measured in feet. f(t) 3.5 30 25 2.0 13 10 0.5 t Part 1: Instructions: Use the information provided in the graph to write an equation for the mathematical model of the tide level in Daytona Beach on this day. Be sure to answer the question and to clearly indicate how you arrived at that answer. Show your work! (Even if using a calculator, show how and why you took the steps you did, not just what buttons you pushed.) Mathematical model: Part II: Instructions: Use your model to determine the tide level at 3AM of the day. Explain your results in the context of the problem and be sure to show how you used your model to get the result.
